Need consumer subscribe topic between latest and earist,which I could give the messageid or seqid.

whatever I use consumerManager or consumer, both I can't position the message to a specified cursor.
This is nessary for my function.

Start by reviewing the consumerManager and consumer entry points mentioned in the issue, focusing on how a consumer chooses its starting cursor. Clarify whether positioning should accept a message ID, sequence ID, or both, and define the expected behavior for positions between the latest and earliest messages. Done means a consumer can start from the specified cursor.
